a) Temperature rise test. b) Switch electrical test.

c) Vibration test. d) Luminous maintenance characteristics and aging test. e) Functional inspection of lamps and lanterns. 4. Inspection instructions: 1. Electrical parameters:

a) DC-powered lamps controlled by an external power supply: voltage and current measured with a voltage and ammeter. (Note: To measure current, you need to measure the current of a single LED lamp and a single color and record it in Appendix 1)

b) AC-powered lamps with built-in power control: use a digital power meter to measure the voltage, current, power, power factor and other parameters of the lamp.

c) Class I lamps must be tested for dielectric strength, leakage current, and insulation resistance. The electric strength is 1500V between the 220V terminal and the shell, and there is no flashover or breakdown in 1min. Leakage current ≤1.0mA. Insulation resistance ≥ 2MΩ. d) The safety level of lamps can be divided into four types:

Class 0 lamps: non-ground wire lamps, lamps that rely on basic insulation as protection against electric shock, which means that the easily accessible conductive parts of the lamp are not connected to the protective conductor in the fixed line of the facility. If the basic insulation fails, you have to rely on Environment. Class I lamps: lamps with a ground wire. The anti-shock protection of lamps not only relies on basic insulation, but also includes additional safety measures, that is, connect easily accessible conductive parts to the protective grounding conductor in the fixed line of the facility to make it easy to reach The conductive parts will not be charged in case of basic insulation failure.

Class Ⅱ lamps: non-ground wire lamps, anti-shock protection not only depends on basic insulation, but also has additional safety measures, such as double insulation or reinforcement, but there is no protective grounding measure or depending on installation conditions.

Class III lamps: The protection against electric shock relies on the power supply voltage being a safe and extra-low voltage (the effective value of the AC voltage is less than 50V), and will not produce lamps with a voltage higher than SELV. 2. Optical performance parameters:

a) Light intensity (cd): The light intensity distribution curve, isoluminous intensity curve, and light intensity distribution data table can all be measured with a Goniophotometer. b) Luminous flux (lm): The total luminous flux and effective luminous flux are subject to the test data of the spectrum analysis system. The area luminous flux table and the ring-belt luminous flux table can be measured with a Goniophotometer.

c) Illuminance (lux): Illuminance distribution and iso-illuminance curve can be measured with a Goniophotometer. d) Color temperature (k): It can be measured with a spectrum analysis system. 3. Structure appearance:

a) The shell structure materials are generally copper, stainless steel, iron, aluminum, plastic PC or others.

b) The types of lamps so far include street lamps, floodlights, downlights, tunnel lights, bulb lights, explosion-proof lights, fluorescent lights, etc. c) Weigh the weight of the lamp.

d) The label of the lamp generally includes the lamp's rated voltage, power, ambient temperature, IP rating, lamp model, manufacturer, etc.

e) Luminaire protection level, according to the requirements of "GB4208-1993" enclosure protection level (IP code), check whether the structure of the luminaire meets the protection level required by the design. 4. Reliability test: a) Temperature rise test, which measures the temperature of specific components when the maximum power consumption of the lamp is working under a specific temperature environment. In addition to the components to be tested according to the testing requirements, the driver IC, lamp housing, LED (lamp pin) Or LED heat sink) and other components are fixed measurement points. It is recorded every 30 minutes until the temperature of each measuring component is constant, and the recording includes the power-on time, the temperature of the measuring component, and the ambient temperature at that time. The record sheet is shown in the second table below.

b) The electrical switch test is to switch on and off for 1 minute and off for 30 seconds as a switching cycle under normal working conditions of the luminaire. According to this, perform the switch test 100 times continuously and record the working condition of the luminaire.

c) Vibration test is to place the lamp on a shaking table and vibrate for 30 minutes to check whether the parts of the lamp are loose or fall off, and whether the lamp can work normally.

d) In the reliability test, check the function items of the lamp according to the lamp instruction manual. 5. Test report:
